Eyepieces, current telescope experience questions? - zhumell 10 inch dobsonian telescope
I mean Zhumell Dobsonian 10-inch telescope had on every occasion since I bought it so. Tonight, the first night in about two weeks, I basically come to use because of bad weather, and I am more familiar with his eyes.
I must confess, my 30mm zhumell Vision 2 inch wide-format is a little more on me every time. This was my first night to be able to see the moon through my Dob10, and I must say that the easiest way to get together with the eyes of the era of 30mm. I think this is the eye of the reduction. But I have some decent individual, even by him.
I also have a look at the moon through my 4mm eyepiece. The only problem wa eye relief. Otherwise, I could very closely and you will see the details about 312x.
I tried againCords through my dob10 with my 30 mm eyepiece and what I got was from what I saw through my eyes otherwise. Thank you to everyone that my goal was good, my eye is normal, and if I then started to burn through the eyepiece has been observed to collect on the cross lines used for the support of my secondary mirror opposite of my reach. Why is this so?
and magazines, to register the image too bright? and the viewing distance is the key to the uptake by the better eye?
I believe that maintaining high performance and low power consumption in each eye of the Baader planetarium.
But I try to find the best price for a good field of vision, eye relief, quality at a reasonable price.
Suggestions?
Especially important to keep your subject arand to see in the field of distance between eyes or vision?

1) read a few eyes! To start Dickinson and Dyer's Guide Backyard Astronomers Starware and Harrington.
2) How are you "burn" through his eyes? Without knowing how to do this, it is impossible to answer.
3) When the secondary support (spider) to see in the center of gravity too.
4) increases above produce less light requiring longer exposure times, a problem with a Dob mount.
Both in the field of view and eye relief is a luxury.
In general, you do not use banks of a large field of view. A significant increase that makes things easier, but do with an equatorial mount, the things even easier. Or a chip reader in azimuth mountain that is important to you. If you look at the planets or binary, then to want the center line and then a relatively simple eye can provide images with better quality. The possibility of finding the object on the edge of a large estate that is good, but if you stop in the middle, then you can not do much. At low magnification wide field will be less necessary, but useful. You can see several pieces of bed sky with more clusters or fog orHE comparisons selection of variables.
With a long focal length eyepiece long eye relief can actually be a disadvantage. The actual viewing distance can be as long as they are far from the lens, which is difficult, the circle is to be found and may lead to additional sources of light in his eyes. In a very short focal length, the opposite is the case, and simple designs look almost unusable. You should consider a Barlow with additional time as a simple method to provide more aid for the eyes. Note that it is a good Barlow should not be cheap, but it is a good alternative to buying a range of focal length eyepiece expensive. If you have only one or two, then maybe it is better in one eye would be better spentinstead.
So my advice is the model you need for each eye for which you choose. Note that the more complex eye could be a better image quality and can cause loss of light from the outer surfaces. Remember to put your money in a layered design and good image quality.
What do you want a record? Registration through the eyepiece? You can use a camera to aim to capture the first target. It seems that the camera automatically focuses on high-contrast, which can be found that the secondary spider. Try to set the target at infinity, more or less where the target is visually oriented for use.
